Note: FT-710 still has CAT issues despite Yaesu firmware updates.
MSHV is a reliable WSJT-X alternative with no issues. FT-710 has issues handling multiple CAT ports. WSJT-X errors due to FT-710 "?" response.
Try MSHV by LZ2HV.
It works great & doesn't error!

Unzip the file & copy CatTouch.fw to FAT32 formatted SD card
This firmware file must be in root folder like D:\CatTouch.fw
Unmount / eject SD card from computer to close file
On FT-710 turn off transceiver & leave CatTouch connected
All other models unplug CAT cable from CatTouch
Insert the card into CatTouch & turn it on (FT-710 turn on transceiver)
CatTouch automatically finds new firmware on SD Card & installs
Do not turn off CatTouch or remove the SD card until it has finished & restarted
Once new firmware installed, Calibrate Touch screen shows
You MUST use the provided stylus & touch each arrow when prompted
If you touch wrong area, touch calibration will detect an error & repeat the process until you get it correct
The trick with calibrating the screen is to put your glasses on & use the provided stylus
The screen has a resistive touch panel so the stylus must be hard & smooth so as to not scratch the screen. A soft stylus will not work.

FT-857 & FT897 are great "shack in a box" transceivers.
With digital modes like FT8 now so popular, a second CAT port is often needed.
If rear CAT is taken up with a tuner or linear, 2ndCAT provides a much needed 2nd CAT port.

Easy set up

Unplug microphone & connect up 2ndCAT adapter as pictured
Select CAT in Microphone Select extended menu #059
Set desired baud rate in CAT RATE extended menu #019

Superior Audio Isolation
High-quality Bourns isolating transformers ensures complete isolation of audio signals,
helping to prevent ground loops and RF interference.

Dedicated USB Audio Codec
Integrated CMedia audio codec converts analog audio to USB data,
delivering crystal-clear sound to and from your computer.
Ideal for digital mode programs such as MSHV, WSJTX, and more.

Adjustable Microphone & Speaker Audio Levels
10-turn pots provide precise control over audio levels,
ensuring optimal clarity for both transmit and receive.
Perfect for fine-tuning digital mode modulation and reception.

Integrated VOX PTT
The VOX (sound activated) circuit automatically keys the PTT (transmitter) when it detects transmit audio from PC.
PTT is opto-coupled which ensures isolation between the transceiver and computer.
Super low 0.18 Ohm FET PTT switching suits both old and new transceiver.

Compatibility
Spports all audio based digital modes like FT4, FT8, JT65, PSK31, RTTY, FreeDV, VARA, Etc
Perfect for bringing older amateur, commercial & military transceivers into the digital age.

Easy Transceiver Connection
Screw terminals for simple connection of transceiver’s speaker, ground, microphone, and PTT.

Supplied with cable gland & case
Solid 3D printed case provides a good level of protection.
PG7 gland secured by case screws.

Easy Audio Configuration
PC microphone and speaker settings control USBRigLink’s receive and transmit levels.
Additional 10-turn pots for fine tuning permanent RX & TX levels.

Plug-and-Play with Modern Operating Systems
C-Media audio codec is natively supported by most modern operating systems.
Eliminates the hassle of installing drivers.
Works with popular PC software such as MSHV, WSJT-X, JTDX, and more.
Even works with FT8CN, an FT8 solution for Android devices!
